Get details about Entrez databases

These functions call the EInfo endpoint. einfo() provides the number of entries in the databases, the name and description, list of terms usable in the query syntax, and list of link names usable with the ELink endpoint.

Usage

einfo(db, ..., retmode = "xml", version = "2.0", .call = rlang::current_env())

einfo_databases(..., retmode = "xml", .call = rlang::current_env())

Arguments

db

name of database to provide information about.

...

additional API parameters (refer to Entrez documentation). Any set to NULL are removed.

retmode

response format.

version

response format version.

.call

call environment to use in error messages/traces. See rlang::topic-error-call and the call argument of cli::cli_abort(). You only need to specify this in internal helper functions that don't need to be mentioned in error messages.
